"Youth gangs and the problems associated with them were once thought to concern a relatively small number of major metropolitan areas whose gang troubles go back to the days of West Side Story. No longer. As the challenge posed by gangs extends to a greater number of cities and to communities of more modest proportions, the need for comprehensive community efforts to address emerging and chronic gang problems intensifies. Dr. Irving Spergel and his colleagues at the University of Chicago have conducted the first comprehensive national survey of organized agency and community group responses to gang problems in the United States. Their study is the only national assessment of efforts to combat gangs. [...] This Summary presents the results of the study team's assessment of youth gang problems and responses across the United States. It demonstrates the need for effective gang suppression and intervention programs. We believe this assessment will help local juvenile justice and law enforcement agencies achieve these goals."
